Low-cost PWM speed controller for an electric mini-baja type vehicle
This paperwork presents a Pulse Width Modulation (PWM) speed controller for an electric mini-baja-type car. A battery-fed 1-kW three-phase induction motor provides the electric vehicle traction. The open-loop speed control ...
New approach of induction machine drive using an adaptive digital PID controller with gain planning based on artificial neural networks
The present work introduces a new strategy of induction machines speed adjustment using an adaptive PID (Proportional Integral Derivative) digital controller with gain planning based on the artificial neural networks. This ...
Controle de velocidade sensorless de motores brushless DC submetidos a variações periódicas de carga
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2011-07-21)
This master thesis presents a sensorless speed control drive of Brushless DC motors used in reciprocating compressors. These compressors cause periodic load torque variations on the motor, consequently mechanical vibrations ...
The cutting time with abrasive discs can be reduced by the control of the cutting speed
This paper presents an experimental study on the life of abrasive discs in cut-off type operations with two conditions of cutting speed. The cutting time is shown with a comparative analysis of the cutting speed.
